Great prime! This has been on my 7D at least 90% of the time since I've purchased it. Abes has new the version with Sigma's new finish which has been working great, although I did have to set MA to -3.

Fast / accurate auto-focus; Nice Bokeh; Rugged; Strong Construction

Chromatic aberration

I bought this lens with the intention of photography active toddlers and doing some night shots. It delivers that and more. Images are very pleasing and same with the bokeh. It's my favourite prime so far (tried Canon's 50mm f/1.4) and highly recommend it.

Perfect lens if it focused properly out of the box. Lens has a little front focus on my Rebel t3i. Sent to Sigma for calibration with camera body still waiting for it to return. Otherwise good quality lens.

I wanted a crop sensor lens that was close to a 50 mm full sensor. I read a lot of reviews, then settled on this lens. I'm a newbie and and still working on my ideal stills but this lens rocks for video

Durable; Easily Interchangeable; Excellent Field Of View; Great for Video; Lightweight; Love The Sharpness

Slight Auto Focus Issues

Purchase use. Very good from F/2.2. Front focus 1.4-2.0. After 2.2 have litle back focus. From f4 focus is perfect. Work very well in life view with Canon 60D. Mutch better than Canon 50/1.8.Very happy.

Have had this lens for about a week now and it produces some amazing images on my Canon 60D.

Image and build quality

The Sigma 30mm F1.4 DC HSM "Art" is a fast prime lens designed exclusively for APS-C DSLRs; it's of particular interest to us because its "normal" field of view corresponds roughly to that of a 50mm lens on a film camera.

Fast F1.4 maximum aperture; Convenient focal length on APS-C; Beautiful bokeh; Excellent center sharpness; Compact and easy to hold; Minimal vignetting at F2 and above; Resistant to flare and ghosting; 4-year warranty (USA; Very affordable

More distortion that we'd like to see in a premium prime; Purple fringing near edges/corners; Low contrast wide-open; Somewhat heavy given its size; Average corner sharpness; Not weather-sealed; Sluggish autofocus

This is a fantastic lens! Since I have had it it hasn't came off my body!

This is a great lens, it exceeded my expectations. Lightroom has automatic corrections for this lens which helps with any vignetting and color distortions at its largest apertures.

Excellent lens with super clarity and ease of use. Autofocus is brilliant. Received superb compliments from my friends and relatives on the pics from this lens. Now i realise ive wasted waytoomuch time with my kit lens.
